Cl. 24256 16 Claims ABSTRACT OF THEDISCLOSURE A device or apparatus having means for controllably winding aweb material being processed and having means for cutting andautomatically starting a new roll to wind the web material without thenecessity of interrupting the feeding of the web material from itssource.

BACKGROUND OF THE INVENTION Apparatus or devices are known which willprovide means for cutting a web material as it is receive-d from asource but such devices do not provide for the automatic delivery andpositioning of an element for winding the web material after it is cutwithout the necessity of stopping the feed thereof so as to permit theremoval of the wound web material from the apparatus while starting anew roll.

The devices presently used, principally in the textile industry areexpensive to manufacture, difiicult to employ and generally requireconsiderable personnel to operate. Further, the interruption of the feedof the textile material as it is being processed through a hightemperature treating zone causes damage to the material within the zonedue to extended exposure to high temperature, Due to the time requiredto cut the material, complete and remove the wound roll and to start anew roll, these procedures are inefficient in operation and increase thecost for treating the textile material.

The apparatus of this invention overcomes the many disadvantages of thedevices presently used in the textile industry and other industriesemploying continuous feed of web material.

The present device allows for the continuous feed of the web materialfrom its source without the interruption of any of the machinery fortreating or processing the material while being wound on a core rod ortube. The device is relatively inexpensive to manufacture, employs anovel means for feeding a new core bar onto the traveling web materialand a novel means for cutting the material so that the cut end willautomatically start to wind on a new core bar thereby allowing for theremoval or dofling of the wound material from the device withoutinterruption of the web material from its feed source. Thus, damage tothe treated web material is obviated and maximum efficiency is achieved.

SUMMARY OF THE INVENTION My invention generally contemplates a newmethod and apparatus for continuously winding and dofiing web materialwhile providing means for cutting the material and starting a new rollwithout interrupting the feed of the web material from its source.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 illustrates the assemblyof the apparatus in which the web material, for example textilematerial, is received from a'feed source, not shown, onto the apparatuswith the material being transported across the winding rolls prior toits completion.

For clarity the following description of the figures will describe thevarious sub-assemblies which comprise my improved apparatus forcontinuously winding, cutting and removing web material from theapparatus without the interruption of the feeding of the web materialfrom its feed source.

The apparatus comprises the following sub-assemblies:

(a) The winding assembly 12 illustrated most clearly in FIG. 2;

(b) The shifting assembly 14 for moving the material being wound fromone position to another on the winding assembly 12 shown most clearly inFIG. 3;

(c) The knife cutting assembly 16 shown most clearly in FIGS. 1, 2, 5and 6; and

(d) The core bar feeding assembly 18 shown most clearly in FIGS. 1 and4.

The winding assembly 12 comprises a plurality of rolls suitably mountedfor rotation on a frame, not shown. The winding rolls preferablycomprise four rolls 20, 21, 22 and 23, each roll being similar inconstruction and having center shaft assemblies 24, 25, 26 and 27mounted at each end of a roll, as seen at roll 20. The outer shell 28 ofeach roll is rigidly mounted to the center shaft assembly by end plates29 so that the shell of each roll rotates with its respective shaft. Theshell of the roll may be made of a different material than the shaft,such as a light weight material, for example, synthetic rubber,synthetic elastomeric materials, such as polyamide, or the like. Asillustrated in FIG. 2, shell 28 is mounted on respective shafts 24, 25,26 and 27 by closed end members 29 so that a hollow annular space isprovided between the inner portion of shell 28 and the respective shaftassemblies. It is obvious that the construction of the rolls may varyWide- 1y, for example, where the rolls are not excessive in length theymay be made of the same material as the shaft and may be solid. Wherethe rolls are excessively long for handling extreme widths of webmaterial the rolls may be made of a material considerably lighter thanthe material forming the shaft so that the rolls when mounted on theapparatus will not bend or otherwise sag due to the excessive weight ofthe roll. The respective shafts are mounted for rotation on theapparatus frame employing bearing mounts, not shown, so that the shaftsare journaled in the bearing mounts for rotation therein. The rolls arespaced from each other a sufficient disance substantially equal to orless than the diameter of the core bar 2 which is employed for windingthe material therearound and which will be discussed more fullyhereinafter. The chain and sprocket assembly coupled to roll 23, as seenin FIG. 2, provides drive means for roll 23. Rolls 20, 21, 22 and 23 arecoupled by suitable chain and sprocket assemblies as shown in dottedlines in FIG. 2 such that all of the rolls will rotate at substantiallythe same speed and in the same direction.

Shifting assembly 14 is mounted on the apparatus so as to be movable aspaced distance along the upper surface of winding assembly 12 formoving the core bar 2 from its initial winding position to its finalposition on winding assembly 12 after the completion of the windingoperation. The shifting assembly comprises a pair of racks 40 mounted oneach side of the frame for the apparatus, not shown, and movableparallel to Winding assembly 12 in rack housing 42. Racks 40 are drivenby a suitable gear or gears, not shown, mounted on shaft 44 in housing42. Shaft 44 has one end extending from housing 42 and has mountedthereon chain sprocket 46. Shaft 50 is disposed beneath the windingassembly and extends across the width of the frame so that its endportions extend beyond shells 28 of the winding assembly and is mountedfor rotation on the apparatus frame by a plurality of bearingassemblies, not shown. Chain sprockets 52 are mounted at each end ofshaft 50. Endless chain 48 is mounted around chain sprockets 46 and 52so that when shaft 50 is rotated sprockets 46 and 52 will rotate andthereby cause the transverse movement of racks 40 either in a forward orbackward direction depending upon the rotation of shaft 50. Drive means54 comprises a reversible electric motor 56 having a driving shaftextending therefrom, not shown, with the end of the shaft mounted togear box assembly 58. Electrically operated over-riding clutch assembly64 is mounted on drive shaft 60 between the ends thereof. Drive shaft 60is mounted for rotation with one end mounted to gear box assembly 58 andits other end mounted to bearing assembly 59. Mounted on shaft 60 isdrive sprocket 62. Shaft 66, which is mounted for rotation in bearinghousings 68, has mounted thereon a second drive sprocket 70 with chain72 mounted around sprockets 62 and 70 for rotating shaft 66. A pair ofdrive sprockets 72 and 76 are mounted respectively on shafts 66 and 50with chain 78 mounted therearound for rotating shaft 50. An'electrically operated brake assembly 80 is mounted on shaft 50 forcontrolling the movement of shifting assembly 14. Electric motor 56 isof the reversible type so that upon the proper signal the rotation ofthe drive assembly may reverse the direction of movement of racks 40either in a forward or backward direction as required. Over-ridingclutch 64 is employed to prevent excessive strains and stresses on thegears in gear box assembly 58 and motor 56 when the electricallyoperated brake 80 is in a braking position. Racks 40 are provided withleading and trailing ends 41 and 43. Adjacent the leading end 41 of rack40 is mounted core bar retaining housing 45 for positioning a core bar,not shown, therebetween so that when rack 40 is driven in a forwarddirection the core bar will be traversed along the winding assembly. Thecore bar assembly will be described in further detail hereinafter.

Knife assembly 16 is pneumatically driven and is actuated byelectrically operated valves. Knife assembly 16 comprises an endlesscutting blade or knife 90 which is mounted for rotation on drivenpulleys 92 by shaft or spindle 94. Shaft 94 is mounted for rotation on asupporti g m 6 and ex ends th reth sus t en si ea t e pulley 92 and theother end mounting pulley 98. Electric motor having shaft 102 extendingtherefrom has mounted at its end pulley 104 so that belt 106 may bemounted around pulleys 104 and 98 for rotating knife 90 around pulleys92. Shaft 108 is mounted for rotation in a pair of bearing housings 109and has mounted thereon motor mounting plate 110 for pivotally mountingmotor 100. Supporting arm 96 is pivotally mounted on shaft 108 so thatmotor 100 and cutting knife 90 will rotate in an arcuate directionbetween rolls 21 and 22 when supporting arm 96 is moved in an upwarddirection. Shaft 112 is mounted for rotation on the apparatus frame, notshown, and extends beneath the winding assembly transversely of theapparatus. At each end of shaft 112 mechanical linkage for raising andlowering the cutting knife 90 is provided. A first linkage or rod 114 ismounted on shaft 112 at one end 115 so as to rotate therewith. Pivotallyconnected between supporting arm 96 and the other end 116 of rod 114 isa second linkage 117 which is pivotally mounted at its ends 118 and 119by pins 120 and 121. Mounted on each side of apparatus frame arepneumatic cylinder assemblies 122. Piston cylinders 126 are pivotallymounted on block 128 at one end thereof by pin 130. Piston rods 132which extend from the other end of cylinders 126 are pivotally mountedby pins 134 on the under side of supporting arm 96. Thus as fluid enterscylinders 126 piston rods 132 are extended in an outward. direction sothat supporting arm 96 is moved upwardly in the direction of the knifeshown in phantom in FIG. 5 with mechanical linkage members 114 and 117pivoting so as to form a substantially straight line.

Knife guide 136 is made of a plastic material and has a slot or openingformed along the longitudinal axis of the guide having a depthsubstantially equal to the width of the cutting blade 90 so that onlythe cutting edge 91 of knife 90 extends above the knife guide. Knifeguide 136 is mounted on supporting arm 96 at each end'thereof bymounting bracket 138. A second knife guide 136 is mounted on the otherside of knife'90 in a similar manner and having a similar configuration.Knife guide 136 prevents knife 90 from vibrating in a sinuous mannerbetween pulleys 92 on which the knife is mounted for rotation. Thecutting edge 91 of knife 90 is scalloped and is best illustrated in FIG.9 which shows the points 93 of cutting edge 91 extending through webmaterial 1. Thus as the cutting assembly moves arcuately upwardly, asillustrated in FIG. 5 in phantom, points 93 of cutting edge 91 passthrough web 1 in the direction of the arrow as shown in FIG. 9. Sinceknife 90 is rotating in the direction of the arrow as seen in FIG. 9,the web material is out throughout its width since substantially all ofthe points of the cutting edge pass through the web materialsubstantially simultaneously. The cutting action therefore is one ofpenetration and cutting in a vertical direction and cutting in atransverse direction for a distance of approximately one-half inch.Since knife 90 extends across the entire widthof the web material theknife or effective cutting edge is a plurality of knives which arecontinuous and are defined between points 93 of the cutting edge 91.Knife 90 is an endless cutting band and therefore the width of thematerial is not a limiting factor in cutting the web material 1 sincethe effective cutting stroke of knife 90 is approximately one-half inch.Knife 90 is rotated at a relatively high speed so that the time requiredto cut the one-half inch of material is substantially instantaneousthereby effecting the cutting of the web material in a substantiallystraight line.

Core bar feeding assembly is generally illustrated in FIG. 1 withdetailed views in FIGS. 3 and 4 showing various components and operationof the assembly. Side panels 140 are mounted on each side of apparatus10 'ad-. jacent the ends of the center shafts of the winding rolls, Acore ba chut 142 which defi e a s b t nt a y te path illustrated indotted lines in FIG. 1 is mounted on the inner surface of panel 140 sothat the discharge end is positioned over the center line betweenwinding rolls 20 and 21. A pneumatic-ally operated valve 144 is mountedto a piston cylinder 146 having fluid inlet and outlet openings 147 and148. Piston rod 149 is pivotally connected at its outer end to plate150. Plate 150 is mounted to a rotating shaft 152 and mounted thereon iscam 154 shown in dotted lines with a core bar being held by the ridge ofthe cam extending into the'chute 140 as seen in dotted lines in FIG. 1.Pneumatic valve 144 is connected to cylinder 146 by flexible hoses 155and 156. When pneumatic valve 144 is electrically actuated pneumaticfluid is caused to enter cylinder 146 thereby extending piston rod 149in an outward direction. This causes plate 150 to move arcuatelyoutwardly and thereby rotate cam 154 so as to release core bar 2 beingheld by cam 50 to move or roll down chute 142. Mounted on core barhousing 45 is a vertically extending rod or bar 157 which extends to apoint which intercepts chute 142 at its upper end. Thus when core bar 2is released by cam 154 core bar 2 will roll down the chute until it isstopped by vertical bar 157. As shifting assembly 14 is moved to thestart position as shown in FIG. 1 so that core bar housing 45 ispositioned below the exit point of chute 142 core bar 2 is controlledduring its descent along chute 142 at a relatively slow rate. When corebar housing 45 is at the rest position vertical rod 157 releases corebar 2 so that it contacts the pneumatic core bar positioning device 158as seen in FIG 4. This device comprises a substantially horizontallyextending bar 159 which is rigidly mounted on a rotatable shaft 160.Also mounted on shaft 160 is a second member 162 which is pivotallymounted to an air cylinder assembly 163. The weight of core bar 2 causeshorizontal rod 159 to move in a downward direction as shown by the arrowin FIG. 5 and into core bar retaining housing 45 mounted on shiftingassembly 14. Due to the weight of core bar 2 air or other pneumaticfluid is expelled from the air cylinder assembly 163. Rod 159 continuesin a downward direction until core bar 2 is dropped onto core barrelease pin 164 which is pneumatically operated and electricallyactuated. When core bare 2 contacts core bar release pin 164, core bar 2is in position for starting a newroll of web material after the webmaterial is cut by the knife assembly.

Shifting assembly 14 is in the form of a channel similar in design tochute 142. A shifter door 166 forms one wall of the channel at theforward end of core bar hous ing 45 and is pivot-ally mounted .at itsupper end. Mounted on its outer face and extending upwardly is bar 168having wheel 170 mounted at its outer end. When the core bar housing ispositioned over the center line between rolls 20 and 21 shifter door 166is closed and held in that position by a fixed track 172 as seen inFIG. 1. When shifting assembly 14 is moved across the winding assembly12 shifter door 166 is held closed by fixed track 172. As core barhousing 45 moves past roll 21 to approximately the center line betweenrolls 22 and 23 of winding assembly 12, track 174 which is pivotallymounted on rotatable shaft 176 pivots upwardly as shown in phantom inFIG. 1 so that fixed track 172 is separated from movable member 178.Shifter door 166 remains closed since whee-l 170 remains in contact withmovable member 178. When shifting assembly 14 begins its backwardmovement to the rest or start position, as seen in FIG. 1, wheel 170disengages from moveable member 178 and does not contact any othersurface so as to permit shifter door 166 to pivot outwardly so as torelease core bar 2 to cause the same to fall over the material webbetween rollers 20 and 21 The weight of the core bar will cause thematerial web to sag between rollers 21 and 22 and after the web materialis severed by knife 90, the rotation of rollers 21 and 22 will cause thenew leading edge of the web material to wind about the new core bar. Theweb material will continue to be wound between driven winding rolls 22and 23. As core bar housing 45 passes onto track 172, wheel of shifterdoor 166 will contact the surface of fixed track 172 so as to closeshifter door 166. Thus, by employing pivotally mounted track 174 meansare provided for opening shifter door 166 which is pivotally mounted atone end and is moved to an open position by a spring-loaded hinge.Further, by employing pivotal track 174 means are provided for expandingthe width of the roll of web material to a greater diameter than thedistance between fixed track 172 and the upper surface of the windingrolls. Pivotal track 174 is mounted on rotatable shaft 176 at one endthereof. Also, pivotal arm 180 is mounted on rotatable shaft 176 at itsinner end and is pivotally mounted to piston rod 181 at its outer endwith piston rod 181 being disposed in piston cylinder 182. Pivotal track174 is pneumatically controlled by piston assembly through pneumaticvalve 184 which is electrically actuated. When shifting assembly 14 isat the rest or start position, i.e., in which core bar housing 45 isdisposed over the center line between rolls 20 and 21, the apparatus isset or has completed its cycle for receiving the next core bar which hasbeen positioned on ,core bar releasing pin 164.

FIG. 7 illustrates the pneumatic system for actuating the knife and corebar assemblies, in which air or other gasses may be used, air being lessexpensive is preferred. Air is supplied to the device through air supplyline from a source not shown. Air supply line 190 is connected to anelectrically operated four-way valve assembly 191 by any suitablecoupling means. Flexible tube 192 connects air supply line 190 to theknife cutting assembly 16. Air passing through valve assembly 191 isconducted through pneumatic tube 193, through flexible air inlet tubes194 to the inlet opening 195 of cylinders 126 of the knife cuttingassembly. Thus, when electrical solenoids 196 are energized valveassembly 191 is opened to permit air to pass into cylinder 126. Whenpiston rod 132 has been extended to full stroke, knife 90 will passthrough web 1 and will immediately start in a downward movement byexpelling air through cylinder 126 through flexible conduit 198, thenthrough tube 199 and finally through exhaust opening 200. Air issupplied to the core feeding assembly which is controlled by the variouspneumatic valves through flexible tube 202 which is connected to tube204. Thus there is a constant air pressure maintained in line or tube204 during operation of the apparatus. The various pneumatic valves andelectrical solenoids which operate the various movements of the core barand shifting assemblies operate independently through their own valves.

In FIG. 1 penumatic valve 206 supplies the necessary air pressure foroperating the shifter release pin 164 when electrically actuated.Pneumatic valve 208 operates the core bar lowering assembly whenelectrically; pneumatic valve 184 actuates the shifter door lockingassembly and pneumatic valve 144 operates the core bar releasemechanism.

FIG. '8 illustrates the electrical schematic diagram for the device whenthe web is about to be cut.

When the roll of web material has reached the desired size or diameterand the shifting assembly 14 is in the start or rest position as seen inFIG. 1, limit switches LS7 and LS-2 are closed and LS8 is open. In thisconnection, limit switch LS7 is only closed when shifting assembly 14 isin the start or rest position. If shifting assembly 14 is not in therest position, the knife cutting assembly cannot operate. Knife cuttingassembly 16 is energized by pushing button PB1. Prior to energizing theknife cutting assembly relays shifter forward (SF), shifter backward(SB) and (KD) are deenergized. Theknife motor 100 starts, relays knifeup (KU) and time delay relay (TDR) are energized but knife assembly 16cannot move up to cut the web material until relay (TDR) times out andsolenoid 196 on pneumatic valve assembly 191 is energized. After relay(TDR) times out, the cutting assembly swings arcuately upwardly betweenwinding rolls 21 and 22 toward web 1. However, prior to cutting web 1limit switch LS27 is closed energizing the solenoids to withdraw thecore bar release pins 164 to drop core bar 2 onto web 1 producingtension on the web as illustrated in FIG. 5 so that knife blade 90- willpenetrate and sever or cut web 1 as illustrated in FIG. 9. In thisconnection, it has been found that the timed sequence for dropping corebar 2 onto web 1 occurs to prior to knife 90 contracting Web 1 but issubstantially instantaneous; that is, the time lapse between thedropping of core bar 2 and the cutting of web 1 occurs within thefraction of a second. After web 1 has been cut, limit switch LS-24remains closed and holds relay (9SMR) energized so that core bar releasepins 164 are held in the withdrawn position until shifting assembly 14has moved in the direction of the dotted lines shown in 'FIG. 1. Thatis, core bar retaining housing 45 must pass at least to the center lineof roll 21 before relay (SMR) is deenergized so that core bar releasepins 164 are returned to their extended position. As soon as knifecutting assembly 16 has passed through web 1 at the end of its upwardstroke, limit switch LS-8 is closed energizing the knife down relay (KD)so that the knife cutting assembly will return to its rest position asshown in FIG. 1. When relay (KD) is energized limit switch LS-3 isopened deenergizing relays (KU) and (BC) to stop motor 100 and returnthe knife cutting assembly to the down" position.

At the time web 1 is cut or severed, core bar 2 drops between windingrolls 20 and 21 and immediately a new roll of web material is windingaround core bar 2 and the finished roll of web material is resting onrevolving rolls 22 and 23 and the finished roll is ready to be dottedand removed to its place of storage or its next sequence of operationfor treating the material.

With the cutting assembly in the rest position, that is, with the knifein the down position, limit switch LS-16 is closed and limit switch LS2is opened. With the shifting assembly at its raised or start positionlimit switches LS29, LS7, LS- and LS13 are closed and limit switch LS17is opened. In order to transfer or move the roll of web material beingformed between rolls 20 and 21 button (PB-2) is pressed to energizerelay (SB) and instantly relay (SB-j) contacts are opened releasing themagnetic brake (MB). Relay (SB-k) is closed to magnetize overridingclutch 64. Also relay (SBZ) is closed and the magnetic brake (MB)contactor energizes the motor to revolve in the proper rotation. Asshifting assembly 14 moves away from its rest position limit switch LS31is closed and energizes the solenoid to bring the core lowering armassemby 158 to the UP position as seen in FIG. 5. Also pivotally mountedtrack 174 is brought to the horizontal position and is held by the timedelay relay (TDRb). When shifting assembly 14 reaches the position shownin dotted lines in FIG. 1 limit switch LS13 is opened and deenergizesrelay (SB). With shifting assembly 14 at the position shown in dottedlines in FIG. 1 limit switch LS-24 is opened to deenergize the solenoidto extend core bar releasing pin 164 so as to hold core bar 2 thereon.At the same time limit switch LS-19 is closed. This energizes the relaySP for moving shifting assembly 14 forward and also time delay relay(TDR-b) times out. However, relay (SF-r) closes and starts the motor fordrive means 54 of shifting assembly 14 in the proper rotation. When timedelay (TDRh) times out shifting assembly 14 returns to the restposition.

Limit switch LS17 is a safety limit switch to limit the size of the rollof web material being wound on core bar 2. If the operator fails to pushbutton (PB-2), safety limit switch LS17 will actuate the shiftingassembly 14 so that it will return to its raised position so that theweb material can be out. When shifting assembly 14 is at its raisedposition the following occurs: limit switch LS18 is opened thus stoppingthe movement of the shifting assembly by dllrgizing relay (SF)thisreleases clutch 64 and 8 applies brake 80. When limit switch LS-31 isopened the lowering core arm slowly lowers core bar 2 to release corebar release pin and the solenoid is energized to put the shifter doorlocking bar 174 in a vertical position. With limit switch LS7 closed andlimit switch LS17 opened the apparatus is ready to repeat the sequenceof cutting the web material.

It is apparent that many variations in design and changes may be made inthe illustrated and described embodiments of my invention withoutdeparting from the spirit and scope thereof.
